The landscape combines terrain, aerial imagery, mapped outlines, and height observations. Coverage and dates differ by source. Each building’s inspector identifies its footprint and height source.
Source vintages and acquisition dates are recorded in the downloadable manifests.
The city outline is shown in gold. The model includes a 400-meter context skirt outside it.
Mapped buildings, roads, railways, land use, and water. The acquisition manifest records the extract date.
Additional outlines were extracted from 2014–2015 aerial imagery. They may include buildings since removed and omit later construction. OSM outlines take priority where the sources overlap. County floor counts, when available, have an unspecified observation date.
Lidar heights are used where coverage exists. Elsewhere, building heights are estimated from recorded floor counts, OSM heights, or land-use defaults. Roof shapes are inferred from height data; wall colors and facade details are generalized.
Terrain color comes from NAIP aerial imagery. Trees require both vegetation imagery and suitable height data; the model does not represent a complete tree inventory.
